Im refitting mine this evening as soon as the repair is finished - I thought that the welded barrels was going to be a great special - Im not seeing it though. I have to remove a special to put the hyper 30s on mine and its definitely not going to be the siege systems. Right now, I'm doing close to 1500 percent building damage. Welded barrels have to go.

did a bit better with hyper 30, wondering if lcm 2 now would make it better

It only makes sense to me to tell you the truth - I wish that I would have put the hyper 30s on there from the beginning but just didnt want to ditch the critical hit special in case it was as good as they made it look.
